Abstract :
We report on-chip structures based on ordered dielectric nano-particle chain which can be used to steer and tune optical beams. With different elaborately designed structures, the optical beam can transmit in a negative direction, or totally reflected beyond the normal incidence with a subwavelength nanorod chain. The mechanism of the phenomenon is believed to be due to the symmetry of resonant modes in the dielectric nanoparticles. With the low-loss feature and the ultra-compact characteristic, this structure may find applications in photonic circuits.
